DUMPING-CAR.

Specification of Letters Patent.

PatentedNov. 24, 1914.

Application filed January 25, 1912. Serial No. 774,128.

To all whom it may concern Be it known that I, CARL P. As'rRoM, a citizen of the United States, residing at EastlOrange, in the county of Essex and State of New Jersey, have invented certain newand useful Improvements in Dumping- Cars', of which-the following is a full, clear,

aridexact specification.

- Thisin'vention relates to dumping ears,

"andha's' particular reference to the constructio'n' of adumpmg car of considerable length for transporting dry and bulky materials suchas ashes, and which can be readily dumpedpreferably by a tilting and lateral movementwvithout distorting the car body,

andalso permitting the parts of the car body tobe renewed where necessary.

" "I-lretdfore,' the length of dumping cars "embodying the invention,

having the motor at one end hasbeen restricted'beeause' when the length became e "ees'si've, the car body would tend to twist -and" become distorted, ultimately breaking 'apart. *-Tl1e result has been that only ear bddies "of comparatively short length and siiiall'capacity have been built with the mo-- ctr atone end, to transport dry and bulky materials.

is the object of this invention to overcome these difiiculties and to provide a car bodyivhich can be of considerably greater l erigthand greater capacity than those hereto'foi'e built,'and which will carry a corn- "paratively larg'e quantity of light material. In order to accomplish this, I propose to "construct a tilting laterally moving car frame' operated by a motor located at one end in such manner that one end of the body will not'be twisted relatively to the other when the motor operates, that is to say, the

power'will be substantially applied to both ends of the car body at once, thereby elimij'ui-ting torsion even in a long body.

The'invention will be more fully understood in connection with the accompanying drawings where1na dumping ear nd Fig. 2 is a perspective view partly in section showing Figure 1 is an elevation of the details of construction. p 1 represents an under-frame carrying cross frames 2, at each end and wheel trucks 3.

4 represents a fluid pressure operated reciprocating motor having a fluid cataract or dash-pot cylinder 5 for controlling the re ciprocation, the movable element of the motor being connected by means of a trunnion 6 to a rolling gear 7 supported by a track 8. At the opposite end is provided a similar gear 7 and track 8, these two gears and tracks serving to support both ends of the body so as to move in synchronism.

Moving with the gears 7 are rolls 9 supported on tracks 10 carried by the cross frames and taking the weight of the ear body. 'lhe rolls 9 also constitute end plates as-ll,

of the car body, these being connected by side frames 12 as shown in Figs. 1 and 2; so that the two end plates 11 and two side frames 12 constitute a rigid nuing'and laterally moving frame supported at each end on the cross frames 2 by the roll portions 9.

The mechanism by whichthe motor 'is connected to actuate the car body is not a part of this invention, but is shown and described in Patent N 0. 889,886 dated June 2,

1908, and the preferred form of-fluid checking mechanism for controlling the movement of the car body is shown in Patent No. 882,129 dated March 17, 1908. 3

T he power is transmitted from one gear 7 to the other gear 7 through a central shaft" extending from one gear to the other, and located between the 'side bars 12 as shown in Fig. 2, the shaft being rigidly keyed to the gears and to the end plates 11.

The bottom of the car body is formed of W- The plates 16 are secured to the It will be observed that the side i possible. To coincide with this bend there will be a specially formed bottom plate 21 adjacent each end plate. The side bars 12 are secured to-lugs '22 carried by the end plates 11, and of course, additional bracing could be used to stiffen this rectangular frame if necessary.

By this invention, a tilting and laterally movable car frame of considerably greater length than has heretofore been built can be produced because the torsion is taken by the central shaft and relieved from the car frame, which'latter only takes the strains due to the load.

The angle of bending of the bottom plates will be determined according to the angle of the car body when moved outwardly and tilted, being preferably made so that the ing hot ashes, slag, etc.

material can slide freely by gravity out of the body. In case of burning out, breakage or other damage of any one of the plates 16, a new one can readily be substituted without considerable expense and without keeping the car out of operation for too long a time. It will also be observed that the shaft will not be subjected to extremes of temperature, because beneath and separated from the car body, which is a articular advantage when the car is used or transport Also, it will be seen that the bottom sections can expand and contract independently, by reason of the link connections, without straining the frame or the shaft.

Various modifications and changes may be made in the specific construction herein set forth without departing from the scope of the invention.

Having thus described my invention, what I declare as new and desire to secure by Letters Patent is 1. A dumping car comprising an under frame, and a dumping car body supported thereon comprising a frame made up of sides and supporting ends, and bottom plates carried by the sides.

2. A dumping car comprising an underframe, a laterally dumping car body supported thereon at the ends, said body comprising end plates resting on the under frame, side frames connecting the end plates, bottom plates carried by the side frames, the end plates extending below the bottom plates and having curved surfaces constructed to roll on the under frame, and means for applying power to move said body.

3. A dumping car body comprising sup porting end plates having the lower surfaces curved to constitute rolling supports, side plates connected to said end frames, and

transversely extending bottom plates separably carried by said side frames.

4. Adumping car body comprising supporting end plates having their lower surfaces curved to constitute rolling supports, side frames connected to said endplates laterally of said curved supporting portions, and transversely extending depressed bot tom sections separately carried by said side frames.

5. A dumping car body comprising supporting end plates having their lower surfaces curved to constitute rolling supports, side frames connected to said end 'plates laterally of said supporting portions, an actuating shaft extending through said end plates for operating the body, and bottom plates carried by said side frames and overlying said shaft.

6. A dumping car body comprising supporting end plates having their lower surfaces curved to constitute rolling supports, side frames connected to said end plates laterally of said supporting portions, an actuating shaft extending through said end plates for operating the body, and W-shaped bottom plates carried by said side frames and overlying said shaft.

7. A dumping car body comprising supporting end plates having their lower surfaces curved to constitute rolling supports, side frames connected to said end plates laterally of said supporting portions, and a sectional W-shaped bottom betweensaid end plates carried by said side frames.

8. A dumping car body comprising supporting end plates having their lower surfaces curved to constitute rolling supports, side frames connected to said end plates laterally of said supporting portions, and a sectional W-shaped bottom between said end plates carried by said side frames, said bottom sections being linked to said side frames.

9. A dumping car body comprising supporting end plates having their lower sur faces curved to constitute rolling supports, side frames connected to said end plates laterally of said supporting portions, anactuating shaft extending through and secured to said end plates, gears carried by the shaft at the ends, one end of said car 7 said gears, whereby power is simultaneously applied at both ends of said car body to actuate it without torsional straining.

11. A dumping car body comprising supporting end plates having their lower surfaces curved to constitute rolling supports,

side frames rigidly connected to said end In testimony whereof I afiix my signature plates laterally of said supporting portions, in presence of two Witnesses. and a bottom composed of transverse see- CARL P.
